The house comprises six shipping containers and a cantilevered timber box, with bedrooms and bathrooms in the containers and the kitchen and living area in the timber box.

The upstairs container with the master ensuite projects over the porch to create a covered entrance.

Form follows function’ is the modernist principle by which a building is shaped by its purpose. However, the reverse applies at this house in Church Point, Sydney, where function follows form due to the challenges of the brief and constraints of the site.

“We had to create the form of the house based on limitations and the lay of the land, and then configure function within it,” says architect Daniel Raymond. It is because of these challenges and constraints that the house sits so harmoniously in the site, coexisting with the bushland setting.

Daniel and Thomas Martin, or rama, designed the house for David and Nyree Jarvis of furniture design and fit-out studio Elo Silo. “I wanted to build a sustainable house, which meant cutting back on labour, materials and waste, and a prefabricated system seemed the best way to achieve it,” Dave says. Efficiency in construction time, budget and space were also important, and shipping containers provided a solution to these needs. “It was interesting to arrange the containers, as modules for living, to satisfy the brief and respond to the site,” says Daniel.

The footprint evolved from negotiating the reasonably steep wedge-shaped block, overcoming difficult access and minimising excavation. Planning codes also required the cabbage tree palms be preserved, and the house comply with BAL-29 bushfire requirements.

The house terraces down the site: upstairs sitting level with the hill behind, and downstairs sitting coplanar with the ground.

The house is composed of six 20-foot shipping containers, which reduced labour, saved embodied energy and allowed for a quicker build with all containers craned into place in one weekend. A cantilevered timber box completes upstairs where the crane couldn’t reach the depth of the site. This upper storey sits level with the hill behind, and the lower storey level with the ground below, so that the house terraces down with the slope of the site.

The exterior of the shipping container is expressed and painted to be recessive within the leafy environment. “Cladding would require more materials, labour and expenditure, so the attitude of being efficient and doing things for necessity rather than desire still applied here,” says Daniel. The vertical corrugation is mimicked in the blackbutt timber battens, which contrast with the industrial nature of the containers and complement the natural setting.

Large sliding glass doors open the kitchen and living area to the north-facing deck.

A blade wall separates the master bed from the passage and wardrobe behind.

Ecoply lines the walls and ceilings and kitchen joinery.

Mirror encases the seams and returns of the shipping containers in the downstairs bathroom.

The sofa and built-in bench are also made with Ecoply and soft-pink upholstered cushions.

Window openings were cut out of the containers off-site, and prefabricated glazing and frames installed on-site. The glass panes of the windows and louvres are all the same size, respectively, making for efficient installation. High-quality insulation prevents cold bridging and condensation on the inside of the containers, and a milked hoop pine Ecoply sheet provides a robust internal lining. With limed cypress pine flooring the same colour as the walls and ceiling, the house has a sense of warmth and homeliness.

There is logic to the layout of functions configured within this form. The containers are the private rooms: two bedrooms, a bathroom and playroom downstairs; master bedroom and ensuite upstairs; all face west or south. The timber box is communal space: living, dining, kitchen and deck, facing north and west. In a seemingly simple yet highly effective move, the upstairs container with the master ensuite is shifted forward, projecting over the porch and identifying and covering the entry.

Cutting out the internal walls of each container allowed for larger bedrooms and bathrooms, with the seams and return (maintained for structural rigidity) encased in timber in the bedrooms and mirror in the bathroom. The modest-sized bedrooms have ample storage and windows for light, views and ventilation, and the playroom opens to a deck, swimming pool and native garden.

The living area faces west to views of Pittwater through the trees.

Upstairs, the compressed space of the containers is released as higher ceilings and large expanses of glass open up the kitchen and living space. The covered deck wraps around one of the cabbage tree palms, and panoramic windows offer views of Pittwater through the trees. “It’s a reminder that you’re up in the canopy,” says Daniel.

The laundry, pantry and storage are behind the kitchen, making efficient use of space, and master bedroom, ensuite and a powder room are adjacent to the living room. A blade wall defines the position of the bed and separates it from the passage behind, which is lined with cupboards, doubling as a walk-in-robe. The ensuite has a dark-coloured material palette, like the exterior of the container, and louvres promote cross ventilation, drawing the prevailing north-easterly breeze through living area and bedroom hall.

Dave is a furniture maker by trade and he designed and built the kitchen joinery and the bedroom and living room furniture, using the same Ecoply that lines the walls and ceilings. Sunlight through the trees highlights the beauty of the grain and brings out a soft pink glow in the ply, which is matched in the upholstery and furnishings.

“Ply is Dave’s material of choice and it allowed us to execute something really special,” says Daniel. “It’s right for the house and the setting.”
